I need to find out if an alternative to the CA3083 with higher Ic exists.
Thanks
 


This is not an alternative. The CA3083 is 5 independent NPN transistors. (I did not specify it at post #1)
Searching, I have found the TCA671 which has 200mA Ic. I will connect all the emitters together, so it is ok that two transistors inside the TCA671 have their emitters connected.

Both CA3083 and TCA671 have high Ft, so they are also suitable for HF RF applications.

Any more powerful 5-NPN arrays out there?
 

Because you already know the alternative, why don't you use simple five RF NPNs?

They must be on the same die, to be well matched, so that they do not require emitter resistors in push pull amplifier configurations, so that they run more efficient.

So there is no higher current alternative than the TCA671?
